Kingdom Protista
3 GROUPS OF PHYLA: ANIMAL-LIKE, PLANT-LIKE AND FUNGAL-LIKE
PROTISTS ARE: UNICELLULAR, COLONIAL, OR MULTICELLULAR;
EUKARYOTIC; MOSTLY HETEROTROPHIC; NOT DISTINCTLY PLANT OR
ANIMAL
Animal-Like Protists- heterotrophic

Animal like protists are categorized according to their method of
movement.

Phylum Sarcodina- pseudopods

Phylum Mastigophora/Zoomastigina- flagellum

Ciliophora- cilia

Sporozoa- no movement (just through spores)
Phylum Sarcodina

Free living (freshwater, saltwater,
soil)

Some are animal parasites

Can move with the aid of a
pseudopod (false feet)- move by
cytoplasmic extensions and
retractions of the pseudopod

Engulfs food

Ex. amoeba
Phylum Zoomastigina

Live in freshwater or salt water

Parasitic and disease-causing

No sexual reproduction, mostly use
fission (asexual)

Form cysts and spread from host to
host

Ex. Trypansoma (sleeping sickness)
Phylum Ciliophora

Most complex of this kingdom;
most advanced

Cilia on body (hair-like projections)
help organism ‘swim’

Reproduce asexually through
binary fission and sexually by
conjugation

Ex. paramecium
Phylum Sporozoa

Need host to move around

Ex. Plasmodium that causes
Malaria

CYCLE: mosquito human
liver red blood cells blood cell
breaks spreads to more cells
Plant-Like Protists

Often referred to as algae

Can exhibit characteristics of both plants and animals

Are plant-like because they have cell walls and
chlorophyll

Reproduction can be sexual or asexual
Phylum Chlorophyta

The Green Algae
Phylum Pyrrophyta

Fire-algae

Produce light

dinoflagellates
Phylum Rhodophyta

Red Algae
Phylum Chrysophyta

Golden Brown Algae
Phylum Phaeophyta

Brown Algae

Kelp
Phylum Euglenophyta

Animal and plant-like features:

Chloroplasts

Engulfs food

Flagella

Ex. euglena
Fungal-like Protists
Phylum Myxomycophyta/Myxomycota

Called slime molds

Body is called plasmodium

Constantly changing shape
